Well, internally yes, but they know they're responsible for an ESC entry and if they are somewhat professionals and know what they're dealing with, they obviously have to take external reactions into consideration.
Plus, I'm pretty sure the Albanian diaspora would be pleased to hear their language rather than English coming from Albania (for nostalgic and patriotic reasons), and the diaspora can't be overlooked when trying to collect televotes, on contrary their support is needed. Albania have a relatively big diaspora group in the Germanic Central-Europe and Scandinavia (in particular Sweden), and also there's the Albanian minority in Montenegro and Macedonia aswell.
